Diesel Engine Heat engines are sometimes referred to as being motors. Actually‚ a motor converts one form of energy into useful work without the intentional production of heat‚ such as an electric motor. A device which burns fuel creating heat to perform work is a heat engine. Heat engines can be classified as external combustion‚ such as steam boiler‚ or internal combustion (IC). They can further be divided into the spark ignited (SI) engine or the compression ignited engine (CI). The compression

of skills are needed to be a successful diesel technician? In order to be an outstanding diesel mechanic you need to have mechanical and technical skills. Diesel mechanics job is to break down an engine and build it back together. They must well know the parts of an engine‚ the transmissions‚ air intake and the exhaust and brake systems. Technical skills include connecting computerized diagnostics equipment to diesel engines to analyze

The Diesel Engine Diesel engines are very similar to the gasoline engine you may find in a car. They both are internal combustion engines‚ have a four stroke cycle‚ and convert chemical energy from fuel into mechanical energy. However‚ the manner in which the combustion stroke is attained sets these two engines apart‚ and although a seemingly meaningless change‚ a large change in efficiency results. (Diesel Engines vs. Gasoline Engines) The diesel engine was invented by Rudolf Diesel in 1892

Christian Libby 2nd hour Auto Tech 1 Tech Report on Diesel Exhaust Fluid Diesel trucks could be run with a lean air-to-fuel ratio‚ to ensure the full combustion of soot and to prevent the exhaust of unburnt fuel. The excess of oxygen necessarily leads to nitrogen oxides (NOx)‚ which are harmful gases‚ from the nitrogen in the air. Selective catalytic reduction (diesel exhaust fluid) is used to reduce the amount of NOx released into the atmosphere. Diesel exhaust fluid (from a separate DEF tank) is injected

Inside this Article Diesel Fuel Injection One big difference between a diesel engine and a gas engine is in the injection process. Most car engines use port injection or a carburetor. A port injection system injects fuel just prior to the intake stroke (outside the cylinder). A carburetor mixes air and fuel long before the air enters the cylinder. In a car engine‚ therefore‚ all of the fuel is loaded into the cylinder during the intake stroke and then compressed. The compression of the fuel/air

Let’s start with the basics. Aside from additives such as ethanol‚ which is made from corn‚ the gasoline and diesel fuel commonly used today derive from the same source--crude oil. Although they share the same parentage (just like motor oil‚ some plastics‚ and Velveeta)‚ they have very different properties. Gasoline is often thought of as being a single chemical‚ but it’s actually a complex mixture of hydrocarbons that generally have 4 to 12 carbon atoms in their molecules. In the case of gasoline

Gasoline vs. Diesel You’re in the market for a new truck; you have an idea about what you want but not quite sure if you want a gasoline or a diesel engine. Well‚ gas and diesel engines are very similar yet different in quite a few ways. At first glance‚ someone who doesn’t know much about either of the two engines might ask‚ “What’s the difference?” To the untrained eye they might look exactly alike‚ but don’t judge the engine by its exterior look. Gas engines are mainly used by the individual

ABSTRACT Crankshaft is one of the critical components for the effective and precise working of the internal combustion engine. In this paper a dynamic simulation is conducted on a crankshaft from a single cylinder 4- stroke diesel engine. A three-dimension model of diesel engine crankshaft is created using SOLID WORKS software. Finite element analysis (FEA) is performed to obtain the variation of stress magnitude at critical locations of crankshaft. Simulation inputs are taken from the engine
